Die Sulfitablaugen aus Zellstofffabriken waren bisher nicht nur vollkommen werthlos,
sondern ihre Beseitigung und Unschädlichmachung bereitete den Fabrikanten sogar viele Mühe und Kosten.
. Bei den Verdampfungsversuchen bleibt ein Product zurück, welches nach Schubert,
Cellulosefabrikation 1897, keinen, höheren Düngerwerth hat. Auch die Versuche, das
Verdampfungsproduct als Futterstoff zu verwenden, führten zu keinen praktischen Resultaten.
The sulphite waste liquors from pulp mills were not only completely worthless up to now, but their removal and rendering harmless caused the manufacturers a lot of effort and expense.
. In the evaporation experiments a product remains which, according to Schubert, Cellulosefabrikation 1897, has no higher fertilizer value. Attempts to use the evaporation product as feed did not lead to any practical results either.
Die Benutzung frischer Bisulfitlauge zur Vernichtung von Rübennematoden ist von geringer Bedeutung und im Uebrigen ist die Einführung freier schwefliger Säure mit der Lauge in den Boden gefährlich.The use of fresh bisulphite liquor to destroy beet nematodes is from The introduction of free sulphurous acid is of little importance Lye dangerous in the ground.
Wohl ist bereits empfohlen worden,' die gereinigte Kochlauge nach Entfernung und Wiedergewinnung der schwefligen Säure als Düngemittel für Wiesen und Felder zu verwenden. Dazu gehört aber ein umfangreicher und kostspieliger Apparat. Einfacher soll sich die Reinigung der Ablaugen mit Aetzkalk in der Wärme und unter Anwendung von Druck gestalten. Diese Schwierigkeiten und Uebelstände bei der Reinigung haben eine allgemeine und einfache directe Verwerthung der Ablaugen bisher verhindert.It has already been recommended, 'die purified cooking liquor after removal and recovery of the sulphurous acid as Use fertilizers for meadows and fields. But this includes an extensive one and expensive apparatus. It should be easier to clean the waste liquor with caustic lime in shape using heat and pressure. These difficulties and evils in purification have a general and simple direct use which has so far prevented the leaching.
Gegenstand der vorliegenden Erfindung ist die Umwandlung der Sulfitablaugen in ein trockenes, festes Düngemittel unter Verwendung von Thomasphosphatmehl.The subject of the present invention is the conversion of the sulphite waste liquors into a dry, solid fertilizer using Thomas phosphate flour.
Zu dem Zweck werden die Ablaugen bis zur Syrupdicke — etwa bis 250B. — eingedampft und mit etwa der gleichen Menge von Thomasphosphatmehl vermengt. Ein Ueberschuß davon schadet nichts.For this purpose, the waste liquors are evaporated to the syrup thickness - approximately up to 25 0 B. - and mixed with approximately the same amount of Thomas phosphate flour. An excess of it does no harm.
Dabei entsteht sofort eine feste Masse, welche sich leicht zerkleinern läßt und einen werthvollen Düngstoff darstellt. Das Thomasmehl wird in Verbindung mit der Ablauge leichter löslich.This immediately creates a solid mass, which can be easily crushed and one represents valuable fertilizer. The Thomas flour is combined with the waste liquor more easily soluble.
Das Thomasmehl wird beim Einrühren in die dicke, schwarz aussehende Ablauge sofort zersetzt; die Masse wird heller, zuletzt braungelb, erwärmt sich ziemlich stark und wird in kurzer Zeit schon so fest, daß man sie mit dem Spaten stechen kann. Neben dem leicht löslichen phosphorsauren Kalk enthält dieser Dünger noch etwas Kali, Stickstoff und reichlich organische Substanz, welche aus dem Fichtenholz herrührt. Das Thomasmehl verliert die durch den Aetzkalk vorhandene Schärfe, indem die freie Säure der Ablauge ihn so'bindet, daß der neue Dünger auch mit Ammoniakdünger gemischt verwendet werden kann.The Thomas flour is immediately when stirred into the thick, black-looking waste liquor decomposed; the mass becomes lighter, finally brownish-yellow, warms up rather strongly and becomes in a short time so hard that you can stab it with a spade. Besides the easy This fertilizer still contains a little potash, nitrogen and plenty of soluble phosphoric acid lime organic matter that comes from the spruce wood. The Thomas flour loses the sharpness present through the quicklime by adding the free acid to the waste liquor binds it so that the new fertilizer can also be used mixed with ammonia fertilizer can.
Die Analysen ergaben, daß dieser neue Dünger ein werthvolles Düngemittel darstellt, in welchem fast alle Phosphorsäure in citratlöslichem Zustande vorhanden ist. Bei Verwendung von Thomasmehl mit einem Gehalt von 18 pCt. Gesammt- und 13,21 pCt. citratlöslicher Phosphorsäure wurde dieCitratlöslichkeit von 73,417 pCt. bis auf etwa 98 pCt. derThe analyzes showed that this new fertilizer is a valuable fertilizer, in which almost all phosphoric acid is present in a state soluble in citrate. Using of Thomas flour with a content of 18 pCt. Total and 13.21 pct. more citrate soluble Phosphoric acid had a citrate solubility of 73.417 pCt. up to about 98 pCt. the
